Host Profile Export BUG #1072

Open MarioRuggieri opened 4 months ago

MarioRuggieri commented 4 months ago

Describe the bug

The export of an host profile via the vSphere web client or via pyVmomi using the ExportProfile method is not deterministic.

Each time ExportProfile() is called the result is different. The same happens via the vCenter GUI.

Reproduction steps

  1. Install pyvmomi via pip3
  2. Use vCenter v8.0.2
  3. Execute the following script:
    
    from pyVim.connect import SmartConnect
    from pyVmomi import vim

si = SmartConnect(host='HOSTNAME', user='USERNAME', pwd='PASSWORD', disableSslCertValidation=True) content = si.RetrieveContent() pm = content.hostProfileManager profile = pm.profile[0] for _ in range(5): print(len(profile.ExportProfile()))


4. The result will be NOT the same, for example this is what happens on my side:

1426335 1426265 1426265 1426265 1426335


5. Go to the vSphere web client, select an host profile, go to Actions -> Export Host Profile -> Save
6. Execute the point 5 many times and observe how the XML changes. For example, in my case sometimes there is the following xml tag inside:
`<string xsi:type="xsd:string">VMkernel.Boot.execInstalledOnly</string>`
and sometimes not.

### Expected behavior

We expect to have the same output string each time ExportProfile() is called.
We expect to have the same XML vpf file each time we export the profile from the vSphere web client.
